Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media used to retain digital data. In addition to local storage devices like CD and DVD readers, hard drives and flash drives, solid state drives can hold enormous amounts of data in a very small device. Cloud services and other new forms of remote storage also add to the capacity of devices and their ability to access more data without building additional data storage into a device.

Hello Experts!

I have a decently spec'd  ESXi host (HP Gen 10) and have Veeam B&R VM working well using a QNAP NAS device as a repository.

I want to create a backup copy job to a USB device. So I plugged the USB disk in, edited the settings for the VM and added the USB device.  All good so far.

So when I logged on to the VM, the drive appeared. I added the disk to the repository and created the backup copy job. But when I ran the backup copy job, it failed after about 10 minutes with the error:

"device is not ready. failed to read from..."

I then tried to copy 50GB of data to the disk through windows explorer and it failed too after a few seconds.  It felt 'bursty'.

I'm guessing this is down to something like polling intervals, a driver or something causing latency. No AV running on the VM (which is Windows server 2016)

IS there any way tweak the configuration to improve performance or reduce latency? Or is passthrough for USB storage just rubbish?

We have a VRTX with VMWare and we need to add more space, thinking in a NAS o SAN to attached we have a Synology NAS with plenty space the one I can use but my question is a good option or we need to get another brand?   any suggestion?
So, I have two sites connected by a gigabit pipe.  I have Veeam at site 1 and it has the vcenter server loaded up and I can see all hosts/VMs at both sites.  I'm replicating, backing up and backup copying like a mad man.  It's working great.

At site 2, I added enough compute and storage to run the entire corporation at site 2 is needed.  

All of my VMs live at site 1, except for a DC and file server at site 2.

I'm using Veeam at site 1 to replicate and backup the two site 2 VMs to hosts at site 2.

What I WANT to do, is replicate everything at site 1 over to site 2 so that is site one goes dead, I can run the company from site 2.

Now, on to my question:

Do I put a Veeam server at site 2 and replicate machines across the pipe to site 2 hosts, or so I add a second replication job at site 1 and send replicas to hosts at site 2?

I don't want two replication jobs running on one VM, if I can help it.

So, what is best practice for Veeam and two sites when you need site 1 to replicate to site 2 for DR?
Boot from SAN and regular Boot

Any Expert to explain the difference between booting from SAN and regular boot.

Thank you
I was reviewing the network setup UCS->Nexus9k->Storage Array. The 10G interfaces on the storage array are setup for 9000 byte MTUs and the Nexus 9k is setup for jumbo frame. But the UCS NIC and VMWare VMNICs are setup for 1500byte frames. This is iSCSI traffic. It all seems to work fine.

I was wondering in this instance what is preventing the storage array from sending 9k frames to UCS/Vmware? Or is it likely sending 9k frames in response to the initiators and the UCS is fragmenting them down to 1500 byte frames? Is there some kind of negotiation between end systems in scenario?
Dell 2950 lost it's RAID configuration.  It has a Perc 6 i controller and an eight drive array.  The operator cleared a foreign configuration so that option is off the board.
 It was originally in a RAID 10 configuration.  All drives are showing as operational.  
I've already chastised the local IT guy for thinking a server would run for 11 years :(
What are the chances of putting all the drives into a RAID 10 configuration and having it operational? Other options?
 This was a domain controller in addition to several other programs.  The data for the other programs was backed up, however the IT guy didn't make a mirror backup of the server :(

Thanks in advance
Hello All;

I was adding another VM in ESXi when I lost connection to it.
Looking over at the server, I noticed all the lights were off of the hard drives, except for 1 drive.
Which would be, I THINK, the 2nd drive. I really did not pay much attention to it, once I noticed the other lights were off.
I brought open the Remote Management console and shut down the server, and then booted it back up.
Going into the Adaptec 6805T Config properties, then into Manage Arrays.
The below screenshot is what I am looking at.

The question(s) I have is as follows.
Q1: The grayed out drive, is this the drive that could potentially be bad?
Q2: They are out of sync in following the regular number pattern. (00,01,02,03)

When I connected the cables to the board. I connected like so.
1 - First (Top first drive)
2 - Second
3 - Third
4 - forth (the bottom drive of the second row, not really sure why I did that for?)
(I removed the cover and checked my cables and they are in fact connected as described above)

The rebuilding % went pretty quickly from 1 to 7, in about 10 minutes.
However, it has been on 7% for about, 10 minutes on its own. Which kind of worries me.
So, it might be that the greyed out drive is in fact bad.
Which in that case, I have two spares, I can replace it with.
I just need some guidance on this one.
Which drive would I remove from the tray and replace it?
And should I shut down the server first, or, keep it on, while it is …
We are relocating our document storage from a server to a NAS. We are curious about how we will be able to maintain the same path. I tried creating a symbolic link in the directory where the original folder was but when I access that share from another computer it tells me I don't have permission to access this resource. I am able to access the NAS using file explorer directly.
When I search Google, I'm directed to articles on downloading software often written by the third party offering said software. Another solution I saw was to create enough large files to consume both the free and purgeable space. How can I remove Purgeable Storage Space on Mac OS without downloading a third-party software?

Perhaps a better question is: do I even need to care about cleaning up my drives before I upgrade to Mojave from macOS High Sierra (v10.13.6)?
Expert out there, I need your help on improving disk latency on a VM.
We have a VM with eight disks that are configured with LSI logic scsi controller with 10 cores vcpu. The backend storage is Dell EMC VNX.
The software vendor ran a simulation and found that the server has disk latency. I was asked to tune the server.
He mentioned that the latency is at 64 KrW and 64KrR and it has to be below 10Ms vs 20Ms.
What would you advise me to do in this case?
We have VMware 6.7 and Dell R730 Esxi hosts in the cluster.
I am building an Oracle Virtual Box VM on a laptop.  I have set the storage on the hard drive to 32 GB fixed.  I run through the install to the reboot.  When it comes back up it wants to reinstall CentOS 8 again and in the Installation Destination window the disc is still 32 GB but only about 1 MB is available.  What am I doing wrong? I follow the book and videos to a  tee but no beans.  And why do I need to reinstall CentOS?  I have set up VMs in VMWare just fine.  I am new to Virtual Box.  Can you help?  thanks.
My Maximus 11 Extreme MoBo has slots for 2 x M.2 drives and a DIMM.2 riser card holds two more. All drives are Intel 660p Series M.2 2280, all are NVMe and share bandwidth on the PCI bus.
All drives were set up and formated using Windows 10 Disk Manager, Windows 10 is current, (v 1909, Build 18363.720). Disk 0 & 3 are 1 TB, drives C:\  &  E:\ respectively. Drives 1 & 2 were formated as Raid 0 stripe, 2 TB, drive D:\.
The problem: Windows resource manager (Disk), does not show a D:\ drive, no less any activity on it.
I'm not even sure if this is a problem if Resource monitor filters out RAIDs. I sure would like to see the activity though!

We have two servers connected directly to a HP MSA2052 SAN using ISCSI
One volume holds our VMs and belongs to the Failover clustered storage, the Failover of VMs works smoothly between nodes.

We have another volume on the SAN that is mapped to one of the nodes that we want to test Windows backup on. The Disk mounts successfully within the windows environment to drive letter H. (Initially the second volume was also added to clustered storage, but windows server backup was unable to run as the back up of Drive C also contained the Clustered Storage volume).
Windows server backup can successfully backup and restore within the Server OS GUI.
We want the ability to be able to restore the windows backup from the recovery console if needs be.

The server nics are all static as shown in the attachment. The SAN has a clustered IP address on the 192.168.1.* network.
Once booted into the recovery console we can assign IP Addresses via netsh to the 192.168.1.* subnet and one of the 17.16. subnets and can successfully ping the respective IP on the SAN.

What we don’t know how to do is see the volume on the SAN that was mapped to the server as the H Drive, which contains the Windows backup image.

Exchange VMs are hosted on Vmware hosts and the underlying storage is all flash.
Exchange server backups are taken at VMware level (snapshot based) and exchange DB level.
We are considering putting exchange 2016 DB and log drives on thin provisioned disks.
Is there any recommendation from Microsoft in regards to thin provisioning disks at Vmware level and exchange LUNs at storage array level?
And are there any negative effects of doing this?
I have an Access program that uses Azure for some tables.  Currently, I simply put customer information into a table (name, address, purchase, very basic stuff) and then our users can go to a website and see that information (I used ASPRunner.net to build what I needed because I have no clue how to do it otherwise).

This was fine but now my client would like to run a report from the Access program, save it in PDF format, and have that available to the customer.  How would I do this?  I read something about BLOB storage but I have never done anything like that.

I finished building the code in Access that will allow the system to create the PDF file and save it in a folder on their local server.
Hi, I am trying to fix boot of a physical server (OS: Windows 2016), I am stuck at screen "choose an option".
I tried with Troubleshooting option, chkdsk /f /r. Task went completely but without solving the issue.
I tried with 1 to 4 methods listed here:


again, without solving.
Any suggestion?
Server has 3 SAS hard disks (raid 5), and raid volume is OK.

Thank you

Hi I run a mailbox export request in exchange 2013 and I tried to cancel the request as I have storage issue but it never stops still mailboxes export in the network path
I tried all these commands with change status to completed, failed, in progress but nothing happened

At my work place - I regularly see messages like this in Solar Winds warning of latency between ESXi hosts and their data store. I have no idea why 20ms is chosen as the warning level. And I'm not sure exactly what type of latency is being referred to in this context. With ICMP I'm familiar with RTT time. But I imaging this is a different measurement. Does anyone know how vSphere measures "latency" from an ESX to its datastore? From a VM to its datastore? Thank you.

I heard about MS SQL Always on group and FCI, FCI is shared storage failover cluster and it is old school, right?

and what is AAG ? or is it simply means AOG ?  other than AAG, what else name SQL server always on group has ?

why this link : https://www.mssqltips.com/sqlservertip/4717/what-is-sql-server-alwayson/ 

seems say FCI also always on ? just new name ? and it seems AOFCI can allow 2 x nodes to form a cluster but AAG cna't ?which need 3 x nodes to form!
In your environments do you have any VM's that you do not backup as a matter of course? Our admins have sent through 'what we currently backup' in Veeam but a quick cross match to a list of all servers in the domain show some servers are not being backed up at all (which may be purposeful - hopefully!). I was just interested if this is common and examples of VM's where you don't need to backup the configuration/data?

Also in your experience - how easy would it be for an admin to miss something critical in terms of VM/virtual HD in backup selections? Realistic or very rare?
What kinds of security features are typically available with modern NAS storage devices, e.g. what are some of the more common controls to make your NAS device and the data held on it as secure as possible. Obviously is a different beast to say a VM Windows Server but there must be some consistency in terms of logical security controls to put in place regardless of make/model.
I am doing some research on the CIS top 20 controls and trying to decipher what exactly this is suggesting:
"Ensure that all backups have at least one backup destination that is not continuously addressable through operating system calls."

1) In terms of say Veeam backups what is it recommending in terms of backup destinations? What would constitute "not continuously addressable through operating system calls", i.e. if you write your backups to a NAS storage device, and those are replicated to another storage device 20 miles away, how can you determine whether that meets the criteria of something that is "not continuously addressable through operating system calls"?

2) From a basic management level perspective, what exactly is "Ensuring that all backups have at least one backup destination that is not continuously addressable through operating system calls" protecting you from/why is it so necessary?
Can file shredders (like LSoft ZDelete) properly shred files on a logical drive on a Windows Server 2008 R2 system using a Hardware Raid controller (Dell PERC H700) configured for Raid 5?

I'm not looking to Wipe the whole drive(s), I want to shred individual files and have the system still work.

If not all shredders will work properly on logical raid drives, does anyone know one that will?
Hello and Good Morning Everyone,

           As an extension to a currently open post, I have a question regarding possible prep work which might be needed before carrying out a laptop hard disk drive cloning.  The new SSD (Solid State Drive) has a storage capacity of 1 TB.  Before I begin carrying out the cloning, will this drive need to be partitioned and formatted?  Here is a link to this drive just in case more technical or detailed information is needed about this drive:  https://www.amazon.com/gp/product/B07L3D19MY/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
The source drive or loaded drive is 500 GB and the target drive or blank drive is 1 TB.

            Thanks in advance for any attention and feedback given to this question.
